Abstract
PDF - Background
This study aims to validate the short version of the Intolerance of Uncertainty Scale-12 (IUS-12).
Methods
A comprehensive set of questionnaires, including the IUS-12, STAI-T, PSWQ, CES-D, and K-CSI, was administered and completed by 404 participants. The average age of the participants was 31.29 years (SD=9.18), comprising 114 men, 287 women, and 3 individuals identifying with the other gender. We conducted a factor analysis on the collected data and compared the fit indices of one-factor, two-factor, and bifactor models. Furthermore, a multiple-group confirmatory factor analysis evaluated measurement invariance between the men’s and women’s groups. Correlational analyses were also conducted.
Results
Data from the study show that the bifactor model was the most appropriate, demonstrating good internal consistency. The Omega coefficients and explained common variance were computed to evaluate the dimensionality of the IUS-12, validating the use of the total score of the scale. Its factor model also showed that the measurement invariance sustained between two gender groups. The correlation analyses between the IUS-12 and other scales assessing attributes such as trait anxiety, worry, depression, and avoidance coping strategy supported convergent validity.
Conclusions
These findings suggest that the IUS-12 is a reliable and valid measure for assessing the intolerance of uncertainty. The study also discusses its limitations and offers recommendations for future research endeavors.

Abstract
PDF
Background: The purpose of this study is to investigate the mediating effect of negative problem orientation in the association between intolerance uncertainty and worry.
Methods: Participants who were 531 undergraduate students in Chungbuk were administered Intolerance Uncertainty Scale (IUS), Negative Problem Orientation (NPO; SPSI-R), Penn State Worry Questionnaire (PSWQ).
Results: The results are as follows. Intolerance of uncertainty had statistically significant positive correlation with worry. Negative problem orientation had a partial mediating effect in the association between intolerance uncertainty and worry.
Conclusions: This result suggested the importance of intolerance of uncertainty and negative problem orientation in psychological approach to university students who have difficulty in worry.

Abstract
PDF
Background: The aim of the present study was to investigate the psychological mechanisms of the variables affecting speech anxiety.
Methods: A total of 550 undergraduate and graduate students, who agreed to take part in the current study, participated and data were collected through online survey. A serial multiple mediated model was tested using the SPSS macro by Hayes.
Results: Internalized shame and intolerance of uncertainty completely mediated the relationship between evaluative concerns perfectionism and speech anxiety. Serial multiple mediating effects of internalized shame, and intolerance of uncertainty were also verified.
Conclusions: These results suggest that intervention on trait variable that targets the internalized shame and intolerance of uncertainty may be helpful in reducing speech anxiety in undergraduate and graduate students.
